Could it work in a real home though?
We don't all have spacious showroom fresh homes. The homes they use to promote vacuum cleaners are already clean, and so spacious and empty, obviously no one lives there anyway.
How would this cope with silly things like, I dunno, socks on the ground, plugs on the ground, coat hangers, cables, litter, empty beer bottles, towels etc?
I don't know about you but before I vacuum, it is not optional to pick up the crap on the floor first.
